我的东道国必须把倾听的日程安排在什么地方?
原标题:What host do I have to bind a listening socket to?

我使用了普思松的袖珍模块,并试图利用听器开张。

import socket
import sys

def getServerSocket(host, port):
    for r in socket.getaddrinfo(host, port, socket.AF_UNSPEC,
                                socket.SOCK_STREAM, 0, socket.AI_PASSIVE):
        af, socktype, proto, canonname, sa = r
        try:
            s = socket.socket(af, socktype, proto)
        except socket.error, msg:
            s = None
            continue
        try:
            s.bind(sa)
            s.listen(1)
        except socket.error, msg:
            s.close()
            s = None
            continue
        break
    if s is None:
        print  could not open socket 
        sys.exit(1)
    return s

东道国无,港口为15,000。

之后,该方案将接受连接,但只接受同一机器的连接。 我必须做些什么来接受互联网连接?

最佳回答

Try0.0. 这是大部分使用的。

问题回答

第一个问题是,除了区块外,你没有报告,反而造成错误。 第二个问题是,你试图与某个具体接口,而不是INADDR-ANY。 你可能对“当地托管人”具有约束力,而“当地托管人”只接受当地机器的联系。

INADDR_ANY也被称为0x0000的固定数字,但宏观意义更为深远。

假设你正在使用IPv4(即“普通互联网”这些日子),将袖珍/组合代码从

你们需要与你的公共IP地址或“所有”地址挂钩(通常用“0.0.0.0”表示)。

如果你试图通过网络进入,那么你也可能需要考虑防火墙等。
